Outdoor Extender Options

I bought Netgear Orbi RBK853-100CNS Tri-band Mesh WiFi 6 System from Costco. Love it. I am not looking to extend wifi coverage outdoors. Since the RBS50Y looks like it is discontinued, what other options would you recommend? 

Also if I just buy a couple of extra satellites any recommendations of what models and where I can get them. I can only find them with a router which I do not need. I live in Canada?

I see posts from 2020 suggesting there is no option as yet. I am hoping netgear has a new option now.

Thanks.
